Up to 0.2 parts per million, or ppm, of volatile organic compounds were detected at multiple locations in Port Arthur and Nederland on Wednesday, according to the latest handheld monitoring equipment data from the Texas Commission on Environmental Quality released Thursday.
Handheld equipment was used to test for lower explosive limit, VOCs, hydrogen sulfide, carbon monoxide, sulfur dioxide, benzene, 1,3 butadiene and oxygen.
